Tb till whom it may} esteem."

I itE wn that I, Aainnro NORiEGA, a citizen of the Republic of Peru,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Ore Classifiers, of whichthe following is" a specification.

This invention relates to ore pulp classifiers of the multiple conetype, and one of the objects is to produce a device of this type inwhich the pulp will be forced upwardly from a nozzle through wateragainst a conical deflector plate from which the various fragments willbe cast ofi to different dis tances according to their specific gravity.

Another object is to provide a plurality of coaxial cones for receivingthe various fragments and conducting them to respective receptacles.

Another object is to provide an adjustable conical deflector plate.

7 Other objects will appear from the following description and claims.All of these objects are attained by the means shown in the accompanyingdrawing comprising one sheet, in which 1 Figure 1 is a verticalsectional view of my improved classifier.

Figure 2 is a horizontal sectional view of the same taken in line 2-2 ofFigure 1, looking down.

Like characters of reference refer to like parts in both views.

Referring to the drawing in detail, 1 represents the framework which maybe of any size or shape suitable to support the working partshereinafter described. A tank 2 is supported on said frame by brackets 3or in any other desirabl manner. This tank is provided at its top with acollar 4 which is secured to the tank by soldering, riveting or in anyother desirable manner, a space or channel 5 being defined betweenmembers 2 and 4. The bottom of collar 4 is inclined toward one side, andat its lowest point is provided with a spout 6. Mounted on the top ofcollar 4 is a bridge 7 which crosses the top of the receptacle and isprovided in the line of the axis of the tank 2, with an internallythreaded bearing 8 in which is mounted a threaded rod 9 provided at itslower end with a deflector plate 10 in the form of an inverted cone andat its upper end with an adjusting hand wheel 11 or other manipulativedevice.

The bottom of the tank 2 is an inverted cone 12 the lower portion ofwhich is pro- 1'5 which is fitted with a'valve 16.

,Mounted in the member 12 is a similar member 17 having a spout 18 andvalve 19,

said member 17 being held in place by webs 20 which are secured tomembers 12 and 17 as shown in the drawing. Similarly, a third member 21is supported in member 17 and is provided with a spout 22 and valve 23.

A reservoir 24 is adapted to contain the ore pulp and water and thismaterial is forced under pressure through a pipe 24 into a riser 25provided with a nozzle 26 by which the material is directed against thedeflector plate 10.

In use the tank 2 is filled with water and then the ore pulp and wateris started through piping 24 and riser 25. The mud and small particlesare washed by the force of the current over the upper edge of member 2into passage 5 and out through spout 6.

The heaviest lumps, when, they strike plate 10 will be arrested andowing to their weight will overcome the force of the current and settlein cone 21, while the lighter fragments will be carried over the cones17 and 12 by the current.

By opening the valves 23, 19 or 16, the

contents of the respective cones may be drawn off. By raising orlowering plate 10 by the handle 11, the graduation of the particlesreceived by each cone may be changed, or this may be accomplished byincreasing or decreasing the pressure on the pulp.

It is, of course, to be understood that the device may be 'made in anysize desired and with any desired number of cones for separating the oreas required.

While I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of the details may be variedwithout in any way departing from the spirit of my invention, and Itherefore do not limit myself to the exact details of constructionherein set forth,

nor to anything less than the whole of my' invention limited only by theappended claims.

'VVhat is claimed as new is 1. In an ore classifier, the combination ofa tank having a circular wall and a conical shaped bottom, a troughencircling said tank at the top thereof, a plurality of conicalreceptacles mounted in said conical bottom and spaced in convergingrelation to said bottom and to each other, said receptacles beingnormally closed at their bottoms, a conical deflector plate adjustablymounted above said conical receptacles, and means for forcing particlesof ore pulp against said deflector plate whereby the same will bearrested within said receptacles according to their specific gravity.

' 2. In an ore classifier, the combination of a tank having a circularWall and a conical shaped bottom, a trough encircling said tank at thetop thereof, a plurality of conical receptacles mounted in said conicalbottom and spaced in converging relation to said bottom and to eachother, said receptacles being normally closed at their bottoms, aconical deflector plate adjustably mounted above said conicalreceptacles, and means for forcing particles of ore pulp against saiddeflector plate, said means comprising a reservoir for the reception ofthe ore pulp and Water, and a pipe connected With said reservoir andleading into said tank and terminating in vertical alignment With theaxis of said conical deflector plate, whereby the ore pulp will strikesaid conical deflector plate and be arrested Within said receptaclesaccording to their sizes or specific gravity.

In testimony whereof I have afixed my signature.

ALBERTO NORIEGA.
